Fuel pressure sensor

[Marie S]

I need help finding my fuel rail pressure sensor. I know it in the engine but where?

 

[Todd Z]

Drivers side of engine, between valve cover and intake manifold. May require removing intake to change, but on the gen 1 I don't think so. Look for the fuel injectors, its in that rail.

If you have the new one. Use it for reference. It is located on the driver side fuel rail. In the pic I put a peice of blue tape on it.

I changed out the part and the light came on again the next day

 

[Todd Z]

whats the Exact code your getting ??

 

[Marie S]

P0193

 

[EddieS'04]

Marie, you seem to have two threads going about the same issue. Makes it hard to help you . I have been posting on both.

Yes I do. I'm trying to get more comments but it didn't work

I know this is an old thread but I got this video in my youtube play list today, explaining this exact part/code



"Come along as I show you how to repair a code P0193. This fuel pressure sensor is very easy. The 2004-2005 Ford Explorer Sport Trac are the same procedure."

If fuel pressure isn't right I'd also be looking at the fuel filter and checking the pressure on the rail. You can buy a fuel pressure gauge that fits the the schrader valve (just like the valve on a tire) on the fuel rail for about $40.

I think on my 2001 Sport trac (october build) the fuel pressure regulator is on the rear of the fuel rail wedged inbetween the engine and the firewall; very difficult to get at.

Very instructional video, great explanantion. Thank you.
However, how does one “reset” the codes? Is it as “simple” as disconnecting one’s negative battery cable for 10-15 minutes? I have a 2004 ST XLT 6cyl 4.0 l engine. Thank you for response.

That might reset it. If you have a code reader. It should have a clear code function. Other than that, if the problem is fixed. It will reset after a number of drive cycles.

Thank you for response. I appreciate it.

1997~2003 YearModel V6~4.0L~SOHC engines usually do NOT have a FuelRailPressureSensor;
for 2004+Later, these same engines usually do have an FRPS Ford# 3f2z-9g756-ac \ cm5229
typically mounted on the left FuelRail behind the EGRValve.

So I changed the fuel sensor, I found it at ParksGeek. (I think that’s the right site) for $60 with shipping. And the engine light has not come on since. -it’s been on for a week now-

 

[mrpeabody56]

I just received pressure sensor (Bosch p/n: 0261230093003) online for $26. It was correct part for my vehicle. Was rated very highly by all who have purchased before. I returned an “Auto ZOnes” sensor, same thing except poorer quality for whcih they tried to soak me for $93.

@Marie S.
Was this the second fuel rail pressure sensor failure?

[Todd Z]

only use Motorcraft sensors. Aftermarkets fail quickly.

 

[mrpeabody56]

No, this was the first time my engine even hiccuped. the sensor I received was the exact replacement part for my V6.

 

[EddieS'04]

Knock on wood. I was in a pinch the way my Trac was running. I bought locally a FPS made by Standard. 4 yrs no problems. Paid as much as the MC sensor. I didn't have time to wait 3 days.
All my life I have good luck with Standard brand. I come from the days of 1960 auto repair. I always suspected they were a rebranded name brand.

I read EddieS'04 post - decided to go to O'Reilly's since they sell the Standard brand, and not risk a chinese counterfeit - $90 plus tax, easy swap, I did d/c the neg batt terminal cable; otherwise, followed the video above on YouTube (StephenL's post). So far, so good. Check Engine light is off, seems to run smoothly.
